Increased overweight prevalence among adolescents is linked to Diabetes mellitus type 2 and insulin resistance (IR). This study aimed to compare insulin resistance among adolescents with normal weight and overweight. The subjects of the study were 96 adolescents (35.4 % male, 50% overweight) aged 14-19 years (16.6±0.98). The BMI and waist circumference (WC) were categorized according to the literature. For IR, the HOMA-IR cutoff of 4,39 was used. The chi-square test evaluated the prevalence difference between categories of weight and WC (p <0.05). There were no significant differences among categories and IR prevalence was 2.1%. However, overweight adolescents tended to have higher values of HOMA-IR. According to glycaemia criteria, IR was not observed in the sample.
